Given numbers are 355,286,442,901
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,286,442,901 is 91478530.
Find LCM of 355,286,442,901 with Prime Factorization
| 2 | 355, 286, 442, 901 |
| 13 | 355, 143, 221, 901 |
| 17 | 355, 11, 17, 901 |
| 355, 11, 1, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 17 x 355 x 11 x 1 x 53 = 91478530
Therefore, the lowest common multiple of 355,286,442,901 is 91478530.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
355 x 286 x 442 x 901 = 40433510260
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
355 : 1, 5, 71, 355
286 : 1, 2, 11, 13, 22, 26, 143, 286
442 : 1, 2, 13, 17, 26, 34, 221, 442
901 : 1, 17, 53, 901
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,286,442,901, is 1.
Now, the common factors can be found like this.
355:5x 71
286:2x 11x 13
442:2x 13x 17
901:17x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 17 = 442
Therefore, the value for common factors is 442.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 40433510260/(1x442)
LCM = 40433510260/442
LCM = 91478530
Thus, we can understand that the LCM of 355,286,442,901 is 91478530.
